A sacrament is a religious ceremony or act that is considered a visible sign of inward spiritual grace. In many Christian traditions, sacraments are seen as essential means through which believers receive God's blessings. Common examples include baptism, communion, and confirmation. Different denominations may recognize varying numbers of sacraments. For instance, the Roman Catholic Church acknowledges seven sacraments, while many Protestant churches typically recognize only two: baptism and communion. Each sacrament serves a specific purpose and is often accompanied by rituals and teachings that reinforce the faith of the participants.
